Why do you want a T34?

As above, if you just fit a T34 to a 1600 without doing other mods it will be a useless lag monster. Unless you are looking for over 250bhp and have the other modification to accompany the T34, I wouldn't even entertain the idea.

You would be far better off putting on a Stg 4 T3 with a .48 exhaust housing because it is easier, or something GT based.
